- Why does my sea salt have a best by date? [duplicate]
@Farooq: As the link in this answer shows, culinary “sea salt” certainly can contain anti-caking agents And as the answer explains, the (potential very slight) deterioration that justifies the “best before” date is not caused by the anti-caking agent, but inhibitied by it Best before dates are never meant to be interpreted as “product expires now — discard it”, but just as
- Why is OH- so electrically conductive? - Chemistry Stack Exchange
In high school (or mine, at least), we're taught that H+ ions are very conductive, due to their small molar mass, and by Newton's 2nd Law, higher acceleration, making them more mobile in solution
- Why is a C4 ring impossible? - Chemistry Stack Exchange
Ring strain and principles of aromaticity render such a molecule unstable Each double bond contributes 2 π electrons, and with four double bonds in one cycle in common, there is a total of 8 Compounds with (4n + 2) π electrons (where n is an integer number) are considered as Hueckel aromatic with an additional energetic stabilization e g , in benzene compared to a hypothetical cyclo-1,3,6
- Understanding Pourbaix diagram - Chemistry Stack Exchange
I am recently taking courses in environmental chemistry and I was introduced to Pourbaix diagram I was taught that the lines in the Pourbaix diagrams are equilibrium lines Lets take as an example
- organic chemistry - Why is naphthalenes protonated pKa −20 . . .
A low $\\mathrm{p}K_\\mathrm{a}$ would indicate a strong acid However, naphthalene is an extremely weak acid, and I read online that it can be classified as a weak base Can someone explain this? Does
- How can methane be an alkane? - Chemistry Stack Exchange
Alkanes are compounds which have single bond between C atoms If so,how can methane be a alkane if it only has one C atom which makes it impossible for 2 C atoms to exist and form single bond with
- NaOt-Bu + chloroethane - Chemistry Stack Exchange
What is the major product formed by reaction of sodium tert-butoxide and chloroethane? I thought NaOt-Bu is a bulky base and the major product will be ethene due to E2 But the answer says t-butyl
- How can one explain niobium’s weird electronic configuration?
As cited in an answer to this question, the ground state electronic configuration of niobium is: $\\ce{Nb: [Kr] 5s^1 4d^4}$ Why is that so? What factors stabilize this configuration, compared to the
